The bottom end of the oil filling channel 24 of the extending column 22 is connected to the oil sump 12, the top end of the oil filling channel 24 is connected to the oil holes 26 opened towards the horizontal direction at the top end of the extending column 22, the number and positions of the oil holes 26 in the preferred embodiment all correspond to the number and positions of the sliding surfaces 6, and the grease 14 in the oil sump 12 can be pushed to flow into the oil filling channel 24 through the bottom of each extending column 22, and then flow out from each oil hole 26 at the top end of the extending column 22.

The carrier plate 30 of the preferred embodiment is hollow at the center to form an accommodating portion 32, and a fixed assembly 34 and a positioning assembly 36 adjacent to and disposed around the accommodating portion 32, wherein the fixed assembly 34 includes two movable blocks 38 parallel to one side of the accommodating portion 32, the movable blocks 38 can move toward the accommodating portion 32 or away from the accommodating portion 32, and the positioning assembly 36 includes a plurality of positioning blocks 37 disposed at other side positions of the corresponding accommodating portion 32. When the movable block 38 is moved away from the receiving portion 32, the upper cover 2 of the keyboard can be placed into the hollow receiving portion 32 of the supporting plate 30, and meanwhile, the upper cover 2 is abutted against the positioning blocks 37, after the upper cover 2 is limited by the positioning blocks 37, the movable block 38 is moved toward the receiving portion 32 to fix the upper cover 2 in the receiving portion 32, so as to achieve the effect of allowing the upper cover 2 to be detachably mounted on the supporting plate 30. The bearing plate 30 is horizontally disposed above the oil injection assembly 20, the bearing plate 30 can move up and down between a first position (as shown in fig. 11) and a second position (as shown in fig. 12) via a lifting assembly 31, when the bearing plate 30 is located at the first position, the bearing plate 30 is located above the base 10, when the bearing plate 30 is located at the second position, the oil injection assembly 20 passes through the accommodating portion 32 of the bearing plate 30, and at this time, if the upper cover 2 is disposed on the bearing plate 30, the extending posts 22 of the oil injection assembly 20 extend into the key holes 4, and the oil holes 26 of the extending posts 22 can correspond to the sliding surface 6.

If the above-mentioned components are applied in the process of assembling the keyboard, as shown in fig. 10, the supporting plate 30 is first located at the first position, the movable block 38 of the fixing element 34 moves away from the accommodating portion 32, and the top cover 2 can be placed into the accommodating portion 32 of the supporting plate 30, as shown in fig. 11, and then the movable block 38 moves toward the accommodating portion 32 manually or automatically by using the sensing element to detect the top cover 2, so as to fix the top cover 2. Then, as shown in fig. 12, the supporting plate 30 is located at the second position by the lifting assembly 31, the supporting plate 30 drives the upper cover 2 to move until the extending posts 22 of the oil injection assembly 20 all extend into the key holes 4, each oil hole 26 corresponds to a sliding surface 6 of each key hole 4, the grease 14 in the oil groove 12 can be pushed to pass through the oil hole 26 and be applied to the sliding surface 6 until an appropriate amount of grease 14 is uniformly applied to each sliding surface 6, the supporting plate 30 and the upper cover 2 move back to the first position and are far away from the oil injection assembly 20, the movable block 38 of the fixing assembly 34 moves towards the direction far away from the accommodating portion 32, and the upper cover 2 can be separated from the supporting plate 30 to complete the grease application operation. The process of applying the grease 14 to the sliding surface 6 through the grease holes 26 and the process of moving the carrier plate 30 back to the first position along with the upper cover 2 can also selectively push the grease 14 to the sliding surface 6 and simultaneously move the carrier plate 30 and the upper cover 2 back to the first position for a preset grease injection time, so that the application range and the amount of the grease 14 can be more uniformly applied to the sliding surface 6.

Through the above assembling mode, because the lubricating grease with higher viscosity is coated on the sliding surface 6 of the key hole 4, the grease 14 is not easy to disappear or fade due to the friction action of the keys, the keys can still be kept to move smoothly after being pressed for a long time, the phenomenon that the keys are not smoothly clamped during key operation is avoided, the lubricating property of the keys is increased, and the assembling quality and the service life of the whole keyboard are improved.
